COUPLING .DRAW-BAR.

To all whom it may concern:

Be it known that I, ALVIN i citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulf'lmprovements in Coupling Draw-Bare;

and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertainsto make and f use the'same.

My invention has for its object to provide an vimproved 'car couplerv clraw bar, including coupler head and shank, and involving also an' lmproved process of producing the same.

In accordance with this invention, the coupler shankand a portion of the coupler head are formed out of pressed steel or similar pressed or rolled metal, and the coupler head Vis completed by a supplemental or additional metallicpart that is fmade fast to the head forming ,portions of'thepressed metal, in i the process of forming the coupler.V

The supplementallor component parts of -the'coupler head' areput together in layers,

structure. VThe layers forming the lamiso that the coupler head is made a laminated timate union or welding of the layers. l When plate. In all cases, the layers are securely that of the said layers. l The laminated or re-= the layers are all of pressed metal, 'such asl pressed steel, they may be weldedtogether by pressure while hot, or may be spot welded after they are pressed together. When one of the layers, for example, is a pressed steel plate, and the other is cast steel, the union': lbetween the two may be made vby casting theV hot molten steel against the pressed steel fastened together without the incorporation therewith of any additional parts, other than inforced construction abovedescribed in con-l nection with a coupler head, may also be applied to the back or follower engaging end of the draw bar.

' f laminatedconstruction, such as above indicated, and wherein oneof the layers isI a pressed steel plate and the other a cast steel, maybe accomplished by first pressing` a Steel blank to form the shank and a portion C. MoCoRD, a

" head forming portions thereof, in amold and casting a steel supplemental head form-l ing partfast thereto, in the vprocess of casting the latter. In some instances, the' metal blank may primarily be a fiat steel sheet, but in other instances, it may be a pressed or rolled steel tube. T hisso-called blank, however, may primarily have other original might be a rolled channel.

I The construction above indicated is well adapted to the manufacture of car couplers of the Master Gar-Builders7 type.v Such a coupler designed infaccordance with my invention, may be made much lighter than a Istandard cast steel coupler of the Master.

Car-Builders7 type, while having as great, or even much greater strength and durability, and furthermore, may be manufactured at I Vless cost.

views.

Referring to the drawings: Figure 1 is a ,plan view with some parts broken away,l

showing a coupler of the type wherein the shank and a portion of the coupler head are formed from a rolled steel tube, some parts being sectioned; Fig. 2 is a side elevation of the couplershown in Fig. .1, some parts be,- ing broken away and some parts being sectioned; Fig. 3 is a section taken on the line ma x3 on Fig. 2; Fig. 4: is a section taken on the line w* m4 on Fig. 2; Fig. 5 is a longitudinal section taken through the coupler on the line m5 x5 on Fig. 1; Fig. 6 is a transverse section taken through the coupler head approximately on the line :06 m0 on Fig. 2; Fig. 7 is a perspective view showing a tubular blank from which the shank and a por; tion of the coupler head are formed and the ends thereof being slit; Fig. 8 is a perspective view showing one end of a tube bent to form a portion of the coupler head, and the other end bent to form a portion of the en-. larged end of the shank; Fig. 9 is a'plan view of the coupler, the shank and portions of the ,coupler head of which are .formed from two flat sheets pressed to proper form,

some parts being broken away; and Fig. 10 I trated in Figs. 1 to 8, inclusive, the numeral to form a part of the coupier head, and having the pressed steel Walls of its ends united With supplemental bodies of metal cast fast thereto.

5. A coupIer drawbar having its shank formed from a metallic tube, the said tube having one end split and bent to form prongs that follow the Contour of the coupler head, and a supplemental body of metal cast fast to said prongs and completing the coupler heac.

6. A eoupler drawbar compi'ising a metallic body and an independently-formed metallic head portion made fast to said body in the ,forming of said head ortion.
